Another form of metabrowsing are shopping comparison sites, sites that spider secondary sites for their pricing information on similar products and then place the prices for those products next to each other. For instance, say example.com is a book metabrowser. It would spider sites like amazon.com, chapters.ca, fatbrain.com to acquire pricing information on the HarryPotter? books and then list each price in its own catalog.
ticketmaster.com has already won a case against tickets.com, a metabrowser, who was spidering ticketmaster and then DeepLinking directly into ticketmaster.com.
All in all, one of those difficult TransCopyright issues.
Check out the Metabrowser at http://metabrowsing.sprint.net.au. It's that serial kind of metabrowser.
